What Does 136RE Rail Mean?
The term 136RE rail means a rail profile with a nominal weight of 136 pounds per yard (rail 136 lbs) under the AREMA standard. The "RE" stands for "Railway Engineering," indicating its standardized profile. Compared with lighter rails, 136 pound rail offers higher strength and durability.
136RE rail, also known as TR68 rail,136 lb rail or AREMA 136RE rail, is a widely used heavy rail section in North America and international railway markets. It belongs to the AREMA standard rail system and is designed for high-load, high-speed railway applications.Its robust design supports higher axle loads and reduces wear over long-term operation.
At GNEE RAIL, we supply not only 136RE steel rail but also a full range of railway fastening systems, crane rails such as A75, A100, A120, A150, and customized rail solutions to meet different project requirements.
What Are the Key 136RE Rail Dimensions and Section Details?
Understanding 136RE rail dimensions and structural parameters is critical for engineering selection. Our 136 RE steel rail features a highly optimized design to distribute heavy loads evenly.Below is a typical technical reference table for arema 136re rail:
| Parameter | Value |
|---|---|
| 136RE rail weight | 136 lb/yd (67.56 kg/m) |
| 136RE rail height | 7.315 in (185.8 mm) |
| Head width | 2.938 in (74.6 mm) |
| Base width | 6.5 in (165.1 mm) |
| Web thickness | 0.625 in (15.9 mm) |
| 136RE rail cross section area | ~13.3 in² (85.8 cm²) |
The 136RE rail section is designed with a balanced head, web, and base structure. This ensures proper load distribution and resistance to bending stress. The 136RE rail profile also improves wheel-rail contact performance, reducing maintenance frequency.
What Are the Key Features of 136 lb Rail?
136 lb rail (136RE or TR68) is a heavy-duty, AREMA-standard steel rail designed for high-intensity, heavy-haul, and mainline railway traffic. Key features include a nominal weight of 136 lbs/yd (67.5 kg/m), high strength-to-weight ratio for improved stability, superior resistance to wear and impact, and a standard height of 185.74 mm.
Key Features and Specifications of 136 lb Rail:
- Weight: Nominally 136.3 lbs/yd (67.5 kg/m).
- Standard: Manufactured to AREMA (American Railway Engineering and Maintenance-of-Way Association) specifications, often referred to as 136RE.
- Applications: Ideal for freight-intensive lines, mainline passenger railways, mining operations, and industrial crane systems.
- Performance: Designed to handle heavy axle loads, providing a higher moment of inertia for superior stiffness and reduced deflection compared to lighter rails.
- Lengths: Commonly available in 39-foot (11.9 m) and 80-foot (24.4 m) lengths.
- Compatibility: Typically utilized with 4-hole or 6-hole joint bars (standard 136lb drilling).
Commonly known as TR68 in some international markets, this rail is favored for its enhanced wear resistance and durability in demanding, heavy-traffic conditions.
Why Choose GNEE RAIL for 136RE Heavy Rail Supply?
GNEE RAIL supplies 136RE heavy rail and related track components for railway construction and maintenance projects. All 136RE rail is produced and tested to AREMA specifications, with Mill Test Certificates provided for each shipment.
1. Product Standards and Quality Control
- Standard: Rails are produced and tested in accordance with AREMA 136RE rail requirements.
- nspection: Each batch undergoes inspection for dimensional accuracy. Key measurements checked include:
- 136RE rail dimensions: Head width, web thickness, base width, and section height.
- Straightness and surface condition.
- Documentation: A Mill Test Certificate (MTC) is provided with each shipment. The certificate lists the chemical composition and mechanical properties of the specific rail batch.
2. Available Processing and Customization
Standard inventory lengths for 136RE rail are 39 feet, 78 feet, and 80 feet. Additional processing is available to reduce on-site work:
- Custom Cutting: Rail can be cut to specified lengths before shipping based on project drawings.
- Drilling: Bolt holes can be pre-drilled at the factory according to provided joint bar dimensions and spacing.
- Coating: Protective surface coatings can be applied upon request.
3. Related Track Components
In addition to the 136 lb rail section, GNEE RAIL supplies compatible accessories for track assembly. This allows procurement from a single source:
- Rail clips and fastening systems
- Fishplates (joint bars) sized for 136RE rail
- Track bolts, nuts, and washers
- Rail pads and tie plates
4. Shipping and Packaging
GNEE RAIL packages 136RE rail with timber separators between tiers and steel frame bracing to prevent surface damage and lateral movement in transit. Rail ends and pre-drilled holes are fitted with protective caps, and weatherproof wrapping is applied for ocean shipments.
These measures are designed to ensure that 136RE rail arrives at the destination with straightness and surface condition consistent with mill inspection records. The packaging method is adjusted based on cargo volume and port equipment to support safe unloading at the receiving site.
Frequently Asked Questions (FAQ)
1. What is the difference between 136RE and 132RE rail?
The main difference is the head shape and the weight. While both have the same base width (6 inches), the 136RE has a slightly thicker head, making it heavier and more resistant to wear under high-traffic heavy haul conditions.
2. Is your AREMA 136RE rail suitable for overhead crane tracks?
Yes, while it is primarily designed for mainline railways, the wide base and heavy load capacity make it an excellent choice for heavy-duty industrial crane runways and gantry crane tracks.
3. What steel grades do you use for the 136RE rail?
We supply this rail in various steel grades depending on your needs, including Standard Carbon (SS), Head Hardened (HH), and Fully Heat Treated (FHT). Head hardened rails are highly recommended for curved tracks to reduce wear.
4. Can you provide ultrasonic testing for the rails?
Absolutely. To ensure internal structural integrity, we conduct 100% continuous ultrasonic testing on our rails before they leave the factory. This guarantees there are no hidden internal flaws that could cause track failure.
5. How do I choose the right joint bars for the 136re rail section?
You must use joint bars specifically cast or forged for the 136RE profile. GNEE RAIL manufactures and supplies 4-hole and 6-hole AREMA standard joint bars that match this exact rail section perfectly.
6. Can GNEE RAIL provide customized 136RE rail?
Yes, GNEE RAIL offers customization such as length cutting, drilling, and special coatings based on project requirements.
